Question

A pea plant is the F1 offspring of a true-breeding plant with purple flowers and a true-breeding plant with white flowers. This plant is crossed with one that has white flowers (recessive). What percentage of plants in the next generation will likely have white flowers

Answer 1

Answer:

50%

Explanation:

As given;

A true breeding plant with purple flower: PP

A true breeding plant with white flower:  pp

Cross between these parents = PP× pp

Offspring are =Pp, Pp, Pp, Pp( all are heterozygous purple)

Now cross between this plant and recessive white flower (pp)

Pp × pp

Offspring are: Pp, Pp, pp, pp

50% are white and 50 % are purple.
